To all whom it may concern:

Be it known that I, EMILE GAUDION, a citizen of the Republic of France, residing at itlarolles, Oise, in the Republic of France, manufacturer, have invented certain new and useful Improvements in Machines for the Manufacture of Buttons, of which the following is a specification.

This invention relates to improvements in machines for the manufacture of buttons turned in corozo, bone and other materials, and particularly to machines or lathes in which the plate to be worked to make a button is held sustained during the work against a non rotary claw located in front of the rotary cutting tool.

In the greater number of machines, the plate is held by hand during the work to prevent the same from being disturbed on the sustaining claw. It has however been proposed to substitute for the action by hand the pressure of a rod slidable according to the axis of rotation of the cutting tool and which bears on the center of the plate under the action of a spring or of a balanceweight.

According to this invention, the cutting tool is provided with a slidable rod of this kind of which the end is diamet ally slitted and with a cutting blade which passes freely through such slit and of which the front end is enabled to strike the whole of the surface of the button to be turned. By means of this arrangement, the cutting blade which is enabled to work all the surface of the button is of a single piece and can on that account be easily mounted, taken out, sharpened and adjusted in position without interfering with the operation of the slidable slitted pressure rod through which it passes.

The accompanying drawings show by way of example one embodiment of the improved machine according to this invention.

Figure 1 is a longitudinal section of an improved cutting tool. Fig. 1 includes perspective views of the parts of the cutting tool detached. Fig. 2 is a cross section on the line AA of Fig. 1. Fig. 3 is a side view of a button of which the back face is turned. Fig. 1 is a cross section of a plate when being worked and of a claw against which the said plate is applied. Fig. is a cross section of a claw, and of a button having both faces turned, the button being shown separated from the plate. Fig. (3 is i MACHINE FOR THE MANUFACTURE OF BUTTONS.

a plan view of a lathe for the manufacture of buttons. Figs. 7 and 8 represent a vertical section and a side elevation of a lathe.

The blade 1, of which the front end 2 is so cut and shaped as to make up the top of the buttons, is slipped into the interior of a carrier composed of a body part 3 and of a sleeve 4 secured together with a screw 5. The body 3 comprises a threaded part screwing into the shaft of the lathe and, at the opposite side, a hollow cylindrical part the outer diameter of which corresponds with the width of the blade 1, and in which are provided two slits 6 for receiving such blade. The fastening of the latter is insured by means of two screws 7, screwed into the thickness of the sleeve 1 and pressing the blade 1 with their points against the edges of the slits 6. The position of the blade in such carrier is so adjusted that it passes a little beyond. the correspoiuling end 8 of the body part 3. The pressure rod 9 is slidable in the interior of such body part, and the front part of such rod is diametrically slitted to receive the blade 1 and is enabled to pass a little beyond the latter as shown in the drawings.

In the lathe shown in Fig. 6, the shaft 11, on which is secured the tool carrier 3 and which revolves in the bearings 13 and 14, is ')rovided with an axial bore through which the rod 15 is slid-able; the outer end of the latter is sustained against a cross-bar 16, which is carried by two rods 17 parallelly guided in bearings 18 and drawn upon by the springs 19. Under the action of the springs 19, the rod 15 pushes the rod 9 outwardly as shown in Figs. 1 and (5. The advance of the rod 9 is limited by a nut 20 abutting against the tool carrier; it is adjusted each time the blade is sharpened. In front of the tool located a claw 25 secured on a wedge shaped slide 26, which is guided in the standards 27 of the fixed support 28. Such claw is surrounded by a ring 41 1 se cured by means of a rigid support on one of the standards of the support. In axial line with the slide 26 is located a cylindrical rod 2) carrying a spline or key 30 on a part of its length, and guided in a sleeve 31 which is rigidly secured in a bearing 32 integral with one of the standards 27. The outer end of the rod 25) is guided in another arm 33 of the support. Under the action of the spring 3 1, the slide 26 pushes the rod 29 in such a ITltlllIlOl that the end of such spline or key 30 bears on a cam 35 which abuts against the arm 33 and which is free :to turn around the rod 29. The cam 35 comprises a helical contour and a steep incline so that at each revolution of such cam, the rod 29 and the slide carrying the claw are gradually pushed in the direction of the arrow A (see Fig.7)

latter and surrounded by a leather strip 37 or other frictional part, and also of a pulley '38 free to revolve on an eccentric portion 39 of the sleeve 31, the inner face of such pulley being adapted to frictionally engage the said leather strip and carry forward the pulley 36. The pulley 38 is given a continu- L ous rotary motion for instance by means of a It will be understood that if the i leather strip 37 surrounds completely thef pulley 36, there would be constantly contact between such strip '37 and the pulley 38 at the point invariable in this instance, where 1 the circles are tangent, and the rotation of I the pulley 36 and of the cam 35 would be t continual. But Fig. 8 shows that the strip 27 on the pulley '36 presents an interruption belt.

of continuity at 40; the result is that if such strip is brought into contact with the pulley E 38 in turning by hand the pulley 36 by a means of a button 41, the carrying forward 1 by friction would be produced until the said interruption of continuity 40 reaches the tangence point of the circles. With this de vice, all that need be done is to turn the:

pulley 36 slightly by means of the button 11 to put the same in gear with the driving pulley 38 and the putting out of gear is automatically produced when the revolution The machine i of the pulley 36 is finished. thus constituted allows of any of the faces of the button being made up and if desired of the stud or button of the outer Washer being detached. For instance, the operator takes a coroz'o plate 42 and applies the same against the claw 25 (see Fig. 1), then puts the pulley 36 in gear so as to make the said claw advance toward the tool, which revolves continually. Before meeting with the tool, the plate 42 strikes the rod 9 and pushes the same in compressing the springs 19, so that the said plate is pressed against the claw and can be released at once by the operator; the latter therefore can immediately make ready for introducing a fresh plate. The advance being continued, the plate 42 lies attacked and hollowed by the tool as shown at 43 (see Fig. l), then the claw 25 recedes suddenly; the plate is then pushed from the operator by the rod 9 and falls. If the plate comes back at the same time as the claw and has a tendency to adhere thereto, it is detached by the lixed ring 44 which stops the same (see Fig. 7) Afterward the opposite face of the plate will be made up after hav in-g changed the tool and the claw, and the latter must be soshaped as to center the button; such second tool will detach the button completely from the washer.
